When Does the Government Have to Disclose 
Private Business Information in its 
Possession? 
April 24, 2019 
On Monday, April 22, the Supreme Court heard oral arguments in Food Marketing Institute (FMI) v. 
Argus Leader Media, in which the Court is considering the scope of Exemption 4 of the Freedom of 
Information Act (FOIA). That exemption authorizes agencies to withhold from disclosure under FOIA 
“confidential” commercial or financial information that a non-governmental entity has supplied an 
agency. While Exemption 4 has generated significant case law in the lower federal courts, the Supreme 
Court has never—until now—considered the issue. Third parties regularly submit sensitive proprietary 
information to the federal government in a diverse array of contexts, including such varied situations as 
applications for government loans; applications for drug approvals by the Food and Drug Administration; 
military and other government contracts; and settlement negotiations with agencies. As a result, the 
Court’s decision in FMI implicates a public policy debate about the scope of Exemption 4. On one hand, a 
narrow view of the exemption could affect private parties’ willingness to share information submitted to 
the government under these and other contexts. At the same time, financial and commercial information 
may often be associated with federal programs and activities that implicate public health and safety, the 
allocation of federal funds, and other matters of public interest that may warrant public scrutiny. 
Accordingly, a decision that broadens agencies’ discretion to withhold under Exemption 4 may effect a 
corresponding limitation on the public’s access to such important data. In anticipation of the Court’s 
decision in FMI, this Sidebar provides a general overview of Exemption 4 and FMI. 
FOIA and Exemption 4 
Congress enacted FOIA in 1966 by amending the Administrative Procedure Act (APA). Congress 
intended the 1966 law “‘to pierce the veil of administrative secrecy and to open agency action to the light 
of public scrutiny.’” While the original APA contained requirements for agencies to make various 
documents publicly available, the exceptions to disclosure in the APA’s public information section had, in 
the estimation of FOIA’s drafters, “become the major statutory excuse for withholding Government 
records from public view.” FOIA therefore established a general “presumption” of public accessibility to 
agency information. In this vein, FOIA directs agencies to disclose certain types of information

affirmatively, whether in the Federal Register or on agency websites (or in other “electronic format[s]”). 
Moreover, federal agencies are generally required to make agency records “promptly available to any 
person” upon request, and agency decisions to withhold information are subject to review in federal 
district court.  
But while FOIA’s drafters intended to establish “a broad philosophy of ‘freedom of information’” to 
protect certain private and governmental interests, they also exempted specific categories of information 
from the mandatory disclosure requirements of the new law. FOIA contains nine enumerated exemptions 
from disclosure that cover a range of different types of information, such as certain matters “compiled for 
law enforcement purposes” (Exemption 7) and information pertaining to specific reports of agencies that 
are “responsible for the regulation or supervision of financial institutions” (Exemption 8).  
Exemption 4 of FOIA authorizes agencies to withhold certain financial or commercial records that non-
governmental parties have provided to the government. (While Exemption 4 provides agencies with the 
discretion to withhold covered information, it should be noted that the Trade Secrets Act (TSA) imposes 
criminal penalties for the unlawful disclosure of many types of information covered by Exemption 4, 
affirmatively prohibiting certain agency disclosures.)  Exemption 4 specifically states that agencies may 
exempt from disclosure “trade secrets and commercial or financial information [that are] obtained from 
a person and [are] privileged or confidential.” FOIA, however, does not define what it means for 
information to be “confidential,” and, therefore, the task of ascribing meaning to that term has fallen to 
the courts.  
National Parks and the Meaning of “Confidential” in Exemption 4 
The U.S. Court of Appeals for the D.C. Circuit (D.C. Circuit) established the leading test for determining 
whether information is confidential under Exemption 4 in a 1974 case, National Parks and Conservation 
Association v. Morton. In National Parks, the D.C. Circuit determined, based on its reading of legislative 
history, that Exemption 4 was intended to protect the interests of the government in “encouraging 
cooperation . . . by persons having information useful to [government] officials,” as well as those of 
“persons who submit financial or commercial data to government agencies from the competitive 
disadvantages which would result from its publication.” Based on this understanding of the exemption’s 
underlying purposes, the court held that information is “confidential” under Exemption 4 only if 
disclosure is likely to: 
1.  impair the government’s ability to obtain necessary information in the future; or  
2.  cause “substantial harm” to the competitive position of the person from whom the information 
was obtained. 
By confining the meaning of “confidential” to these two, specific situations, National Parks limits the 
grounds under which agencies may withhold commercial or financial information supplied by third 
parties, affording more public access to such information. Nearly twenty years later, in Critical Mass 
Energy Project v. Nuclear Regulatory Commission, the D.C. Circuit limited the National Parks test to 
situations in which entities are obligated to provide commercial or financial information to an agency. If a 
submitter has voluntarily provided the government with financial or commercial information, such 
information, per Critical Mass, “is ‘confidential’ . . . if it is of a kind that would customarily not be 
released to the public by the person from whom it was obtained.” Most federal courts of appeals have not, 
as of yet, embraced Critical Mass’ modification of National Parks. Instead, other appellate courts have 
continued to apply National Parks to both voluntary and involuntary submissions of information.  
Notwithstanding its widespread adoption by the lower federal courts, several commentators, judges, and 
even Members of the Supreme Court have criticized the National Parks test. Critics have contended, for 
example, that the National Parks test is divorced from the ordinary meaning of the word “confidential,”

which usually does not just refer to the two, specific criteria mentioned in that case. The test has also been 
criticized for creating legal uncertainty as a result of lower courts’ varying and conflicting applications of 
the “substantial-competitive-harm” prong of the test. For example, in a 2015 dissent from denial of 
certiorari, Justice Thomas (joined by Justice Scalia) opined that National Parks is “an atextual test that 
has different limits in different” courts of appeals. He wrote that courts do not agree on whether “some 
defined competitive harm (like lost market share)” must be shown to prove likelihood of substantial 
competitive harm, or whether it is enough to show “that competitors’ possible use of the information 
alone constitutes harm—even if this would not likely result in any negative consequences for the entity 
whose information was disclosed.” According to Justice Thomas, such disagreements have generated 
lamentable “confusion” in the lower courts. 
FMI v. Argus Leader Media 
In FMI, the Supreme Court has been asked to abrogate the National Parks test. The case arises from a 
FOIA request for information pertaining to the Supplemental Nutrition Assistance Program (SNAP). A 
reporter with the Argus Leader (Argus), a Sioux Falls, South Dakota newspaper, requested from the U.S. 
Department of Agriculture (USDA) what is known as “store-level redemption data”—data on the amount 
of “money individual retailers receive[] from” SNAP beneficiaries’ purchases. USDA denied the 
reporter’s request and, on appeal in federal court, argued that the data were exempt from disclosure under 
Exemption 4. The district court concluded that the information did not satisfy the “substantial-
competitive-harm” prong of the National Parks test, determining that “any potential competitive harm [to 
retailers] from the release of the requested SNAP data is speculative at best.” The court, therefore, held 
that the information was not “confidential” under Exemption 4 and therefore needed to be disclosed. FMI, 
a food retail trade group representing members that participate in SNAP, intervened in the litigation and 
appealed to the U.S. Court of Appeals for the Eighth Circuit. The court of appeals, relying on National 
Parks, affirmed the district court’s judgment, and FMI sought review by the Supreme Court. 
Before the Supreme Court, FMI offers two arguments. (The U.S. Solicitor General has also filed a brief in 
support of FMI.) First, the trade group asks the Court to abrogate National Parks and argues that, in place 
of that judicially crafted two-part test, the Court should give the term “‘confidential’ . . . its ordinary 
meaning.” Citing FOIA’s legislative history, prior judicial decisions—including the Court’s interpretation 
of “confidential” in the context of another FOIA exemption—and dictionary definitions, FMI argues that 
“confidential” information refers to “information that is kept private and not publicly disclosed,” a 
broader class of information than that which is encompassed by National Parks. Echoing Justice 
Thomas’s 2015 dissent, FMI argues that the National Parks test is “atextual” and responsible for multiple 
unnecessary inter- and intra-circuit splits on the application of the test. FMI claims that the store-level 
redemption data qualifies as confidential under the ordinary meaning of the word, asserting that “retailers 
carefully safeguard” this data and noting that USDA has “longstanding policies” assuring its 
confidentiality.  
In the alternative, FMI contends that the Court should “[c]larify[] that the National Parks test is met when 
there is” merely “a reasonable possibility of financial or commercial harm—which, in the context of a 
business, means the possibility of diverted sales or profits.” FMI’s proposed test would expand 
Exemption 4’s coverage and, FMI argues, have the salutary effect of “facilitat[ing] uniform application” 
by courts. Under this “clarification” of the National Parks test, FMI contends that USDA’s trial evidence, 
which included testimony that publicizing retailers’ store-level redemption data would cause “competitors 
[to] adjust their product selection and marketing to attract SNAP customers,” clearly shows “a reasonable 
possibility that competitors could use . . . redemption data in ways resulting in harmful diversion of sales 
or profits.” 
Argus supports retaining the National Parks test. (Argus also contends that FMI does not have standing to 
appeal because the U.S. Solicitor General stated in its brief that “USDA would exercise [its] discretion to 
  
Congressional Research Service 
4 
disclose” the redemption data even if Exemption 4 could allow it to withhold, save for the fact that it 
perceived itself as barred from disclosing under another statute.) Specifically, Argus opines that 
“confidential” carries the meaning announced by National Parks because, among other things, at the time 
Exemption 4 was drafted, the term “trade secrets and other confidential commercial information” “was an 
established common-law term of art for non-public business information, disclosure of which would be 
tortious because it would cause competitive harm.” Argus asserts that National Parks’ “substantial-
competitive-harm” prong embraces this understanding of “confidential,” and that congressional 
enactment of over sixty “provisions that either expressly incorporate Exemption 4 . . . or enact a virtually 
identical standard” evince congressional ratification of National Parks.  
FMI’s Possible Impact 
The Court’s decision in FMI could have a significant impact beyond the context of public access to store-
level SNAP redemption data. Were the Court to abrogate the National Parks test and adopt a broader 
definition of “confidential” information, Exemption 4 would allow agencies to withhold a larger swath of 
information from disclosure under FOIA. Critics of National Parks have asserted that the test 
“discourages businesses from disclosing information to the government” out of fear that the information 
will be made public and that adoption of a broader definition of “confidential” will instill greater 
confidence in entities that disclose sensitive proprietary information to federal agencies. On the other 
hand, because much of the information potentially within Exemption 4’s ambit implicates important 
matters of public interest (as mentioned above), supporters of National Parks argue that adopting a 
definition that expands agencies’ discretion to withhold information submitted by third parties would 
undermine the acknowledged goal of FOIA to “‘contribut[e] significantly to public understanding of the 
operations or activities of the government.’”  
At oral argument, the Justices asked each party probing questions that underscored the complexity and 
importance of the case. Justice Kagan, for example, asked counsel for Argus how the present case is 
different from the Court’s 2011 decision in Milner v. Department of the Navy, in which an 8-1 Court (in 
an opinion by Justice Kagan) overturned another D.C. Circuit interpretation from the 1970s that the Court 
described as “ignor[ing] the plain meaning of the” FOIA exemption at issue and imposing a standard that 
had “no basis or referent in [the exemption’s] language.” Justice Gorsuch asked whether it was significant 
that “confidential” has been interpreted differently in the context of another FOIA exemption (Exemption 
7(D)). On the other hand, Justice Ginsburg asked both FMI’s counsel and counsel for the Solicitor 
General whether abrogating National Parks in favor of a broad definition of “confidentiality” was in 
conflict with FOIA’s pro-disclosure aims.  
Should Congress seek to provide clarity on this issue, there are several legislative options 
available to it. Congress can, akin to the TSA, pass legislation independent of FOIA that 
prohibits agencies from disclosing certain commercial or financial information supplied to it by 
third parties. It may also amend Exemption 4 itself. Depending on its view, it could incorporate a 
broad definition of “confidential” similar to FMI’s into the exemption, codify the National Parks 
test, or adopt an entirely different test. It could take any of these approaches regardless of how 
the Court holds in FMI, as Congress can overturn Supreme Court decisions that are based on 
statutory interpretation. Indeed, Congress has previously amended FOIA in response to judicial 
decisions with which it has disagreed.
